1. General
The frequency inverter KEB COMBIVERT F5 is a drive component, which is intended for installation in electrical
systems or machines. The frequency inverter is exclusively for stepless speed control / regulation of three-phase
motors. The operation of other electrical consumers is not permitted and can lead to the destruction of the unit.
KEB COMBIVERT F5 has very extensive programming options. To make the operation and start-up simpler for
the user, a special operator level was created in which the most important parameters are found. However, if the
parameters pre-dened by KEB are not sufcient for your application an application manual is available.

2.2.5 Voltage Input / External Power Supply
The supply of the control circuit through an external voltage source keeps the control in operational condition even
if the power stage is switched off. To prevent undened conditions at external power supply the basic procedure
is to rst switch on the power supply and after that the inverter.

2.3 Operator
As an accessory to the local or external (option: cable 00.F5.0C0-1xxx) operation an operator is necessary. To
prevent malfunctions, the inverter must be brought into nOP status before connecting / disconnecting the operator
(open control release terminal). When starting the inverter, it is started with the last stored values or factory
setting.

Operation of the Unit
3. Operation of the Unit
3.1 Keyboard
When switching on KEB COMBIVERT F5 the value of parameter CP.1 appears (see Drive mode to switch the
keyboard function).
The function key (FUNC) changes between the parameter
value and parameter number.
With UP (▲) and DOWN (▼) the value of the parameter
number is increased/decreased with changeable
parameters.
Principally during a change, parameter values are immediately accepted and stored non-volatile. However, with
some parameters it is not useful that the adjusted value is accepted immediately. In these cases (CP.28, CP.32,
CP.33, CP.34) the adjusted value is accepted and stored non-volatile by pressing ENTER.
If a malfunction occurs during operation, then the actual display is overwritten by the alarm message. The alarm
message in the display is reset by ENTER.
== Error ==>
With ENTER only the error message in the display is reset. In the inverter status display (CP.3) the
error is still displayed. In order to reset the error itself, the cause must be removed or a power-on
reset must be made.

Parameter description
CP.15 Boost
Co-domain Setting Description
0.0…25.5 % 2 %* In the lower speed range a large part of the motor voltage decreases on the
stator resistance. To keep the breakdown torque nearly constant over the
entire speed range, the voltage decrease can be compensated by the boost.
Adjustment:
• Determine the rate of utilization in no-load operation
• Preset about 10 Hz and adjust the boost, so that the same rate of utilization
is reached as with the rated frequency.
When the motor, during continuous operation, drives with low speed and too high voltage
it can lead to an overheating of the motor.
CP.16 Rated frequency
Co-domain Setting Description
0.00…400.00 Hz 50 Hz With the adjusted frequency the inverter reaches in controlled operation a

3.2.4 Special Adjustments
The following parameters serve for the optimization of the drive and the adaption to certain applications. These

CP.17 Voltage stabilization
Co-domain Setting Description
1…650 V (off) 650 V (off) With this parameter a regulated output voltage in relation to the rated
frequency can be adjusted. For that reason voltage variations at the
input as well as in the intermediate circuit only have a small inuence
on the output voltage (U/f-characteristic). The function allows an
adaption of the output voltage to special motors. The values must be
conrm by „ENTER“.
In the example below the output voltage is stabilized to 230 V (0 %

(see manual:part 2). The values must be conrm by „ENTER“.
Refer to following list to learn
about inuences and effects of the
switching frequency.
low switching frequency high switching frequency
less inverter heating less noise development
less discharge current improved sine-wave simulation
less switching losses less motor losses
less radio interferences improved controller characteristics
improved concentricity with low
speed (only open loop!)
At switching frequencies above 4 kHz pay absolute attention to the max. motor line length
in the technical data of the power circuit manual (Part 2).

Parameter description
CP.19 Fixed frequency 1 (input 1)
CP.20 Fixed frequency 2 (input 2)
CP.21 Fixed frequency 3 (input 2)
Co-domain Setting Description
CP.19
0…±400 Hz
5 Hz Three xed frequencies can be adjusted. The selection is made by
the inputs I1 and I2. If adjustments are made that are outside the xed
limits of CP.10 and CP.11, then the frequency is internally limited. The
negative values are released in application mode.
The rotation source of the xed frequencies is not changed by CP.34,
it always corresponds to CP.34 = 2.
CP.20 50 Hz
CP.21 70 Hz
Input I1 → Fixed frequency 1
Input I2 → Fixed frequency 2
Input I1 and I2 → Fixed frequency 3
CP.22 DC braking / Mode
With DC-braking the motor is not decelerated by the ramp. Quick braking is caused by D.C. voltage, which is
applied onto the motor winding. This parameter determines how the dc-braking is triggered. The settings must
be conrm by „ENTER“.
Value Setting Function
0 DC-braking deactivated
1DC-braking at switch off of the direction of rotation and upon reaching 0 Hz. The braking time
is CP.23 or until the next direction of rotation.
2 DC-braking as soon as setting for the direction of rotation is absent.
3 DC-braking as soon as the direction of rotation changes or is absent.
4 DC-braking on disabling the direction of rotation and if the real frequency falls below 4 Hz.
5 DC-braking when the real frequency falls below 4 Hz and the drives decelerates
6 DC-braking as soon as the set value falls below 4 Hz.
7 x DC-braking when input I4 is switched. At control circuit B = value "0"
8 DC-braking when input I4 is switched. At control circuit B = value "0"
9 DC-braking after switching on the modulation.
CP.23 DC-braking / Time
Co-domain Setting Description

Parameter description
CP.24 Maximum ramp current
Co-domain Setting Description
0…200 % 140 % This function protects the frequency inverter against switching off through
overcurrent during the acceleration ramp. When the ramp reaches the
adjusted value,it is stopped so long until the current decreases again. CP.3
displays "LAS" at active function.
CP.25 Maximum constant current
Co-domain Setting Description
0…200 % (off) 200 %
(off)
This function protects the frequency inverter against switch off through
overcurrent during constant output frequency. When exceeding the adjusted
value, the output frequency is reduced until the value drops below the adjusted
value. CP. 3 displays "SSL" at active function.

CP.26 Speed search condition
When connecting the frequency inverter onto a decelerating motor, an error can be triggered by the differing
rotating eld frequencies. With activated speed search the inverter searches for the actual motor speed, adapts
its output frequency and accelerates with the adjusted ramp to the given set value. During speed search CP.3
displays "SSF". The parameter determines, under what conditions the functions operate. In case of several
conditions the sum of the value must be entered. The settings must be conrm by „ENTER“.

Example: CP.26 = 12 means after reset and after autoreset UP.
